When I was in the office, sitting in my little half-cubicle, listening to my co-workers yell to their speakerphones in a meeting, interrupting everyone else, losing my concentration, etc--I was STILL working remotely.
My job consists of building, securing, and maintaining servers in a datacenter. Those datacenters were no on the same floor as I was. Most of them weren't even in the same building.
The only difference between then and now as far as my job goes, is I no longer have to commute in one of the world's worst traffic cities, and I'm saving some wear and tear on my vehicles.
Some jobs are telecommuting whether you're in the office or not.
Our team has daily meetings with a director during certain project cycles. On the days he's in the office, it's an absolute waste of time. No one can hear him because a nearby loudmouth drowns out his phone when she's talking. She's so loud it's almost as though it's a comedy skit.
